Cruyff sought revenge and did the unthinkable, penning a deal with the Amsterdam club's bitter rivals Feyenoord

Aged 36 and with eight Eredivisie, one La Liga and three European Cup titles to his name, Cruyff was already a legend of the game by summer 1983. Yet after helping Ajax to another league and cup double, he was rewarded by being told he was surplus to requirements.

Cruyff sought revenge and did the unthinkable, penning a deal with the Amsterdam club's bitter rivals Feyenoord. To rub salt into wounds, the forward helped his new side to their own domestic double, scoring against Ajax in a 4-1 win along the way and earning himself a fifth Dutch Footballer of the Year title.

"I don't care what these people think," he later said in reference to the home support

Now manager of Barcelona, Luis Enrique initially made a name for himself with the Catalans' bitter rivals, Real Madrid. The Spain international spent five years at the Santiago Bernabeu, even emphatically celebrating after scoring against Barça in a 5-0 win in 1995.

Yet just 18 months later he was at the Camp Nou, netting his first goal for his new club against los Blancos in Madrid and celebrating just as exuberantly.

"I don't care what these people think," he later said in reference to the home support. Ouch.
